The CCSV-reducing base stocks include mono-esters derivable from a Guerbet 00 alcohol and a monocarboxylic acid. The disclosure also relates to lubricating oils containing the CCSV-reducing base stocks, and 1-1 N containing one or more of the CCSV-reducing base stocks. [Continued on next page] a method for improving fuel efficiency and/or wear protection in an engine by using as the lubricating engine oil a formulated oil D(kv) 10 FIG. 1 WO 2018/183032 A8 MIDEDIM01101 DIONER131111111111111111111111111011111110#10# (84) Designated States (unless otherwise indicated, for every kind of regional protection available): ARIPO (BW, GH, GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
